The Struggle for South Yemen [PDF ebook] 

South Yemen was long a key spot in the strategic geography of the West. Before the Second World War, it was important for the British as an outpost on the way to India. From the mid-1940s it was a crucial gateway to the oil rich Arabian Peninsular and a vital area in the context of superpower rivalry. This book, first published in 1984, traces the development of nationalist sentiment in South Yemen and the emergence of the two main groups in the struggle for independence: the NLF and FLOSY. Analysing both the impact of these groups on Yemeni society and demonstrating how they struggled with each other for supremacy, the book provides an perceptive account of how the revolutionary process in an Arab country unfolded.
